[R-390] 'Burbs antenna

Sat, 10 Aug 2002 22:13:10 -0400

The balun was just a PVC pipe filled with ferrite cores and the coax ran
through the centers.  The big PVC center piece, conveniently filled with
permanent potting umpumkumpy, contains a high wattage resistor bridging
the two ends of the loop.  Its easy to get a flat SWR when you're
driving a resistor!  Yes it advertised performance "quieter" than a
dipole.  Sure, my dummy load is quieter too!  In case you haven't
guessed, I have a bad taste in my mouth about this product from B&W.
